Advanced Installation Steps
2.5.2.3 SRCU31 Hardware Installation
The SRCU31 comes with the Intel Integrated RAID firmware already programmed into the flash
memory. Note that if the memory DIMM is not provided with the adapter at the time of purchase,
you must install an approved unbuffered, PC100, ECC, SDRAM DIMM into the memory socket
prior to SRCU31 installation. See the Hardware Requirements or refer to the approved memory list
at http://support.intel.com/support/motherboards/server/srcu31
to determine an approved memory
DIMM for use in the adapter.
Warning: Shock hazards may be present inside the unit in which this card is being installed. Disconnect all
power cords to the unit before the removal of any covers.
Follow the warnings noted in your computers user or service manual before installing this board.
ONLY after all the covers are reinstalled should you reattach the power cords and power up the unit
for the software installation and use.
Note: Take precautions to prevent electrostatic discharge (ESD) damage before handling the SRCU31
Adapter Card.
1. Power down the system, disconnect power cord(s) and remove the system cover.
2. Install the SRCU31 into an available PCI slot. Connect one end of the SCSI cable to the
internal (68 pin) or external (VHDCI) SCSI connector on the SRCU31. Connect the other end
of the SCSI cable to the SCSI drives or drive enclosure.
3. Replace the system cover, reconnect power cord(s).
Note: SRCU31 will work in a 32bit slot, however, a 64bit, 33 MHz PCI slot is recommended. Consult the
system guide for the target server board to determine an appropriate 64bit, 33 MHz PCI slot.
Ensure that the ends of the SCSI bus are properly terminated. Consult the documentation for the
drives or drive enclosure for termination details.
